Short answer: the KEF Q3 Meta, if you are buying new. The Revel Concerta2 M16 ranks higher than it (#62 vs #156 of 222 bookshelf speakers, 4.1/5 vs 3.4/5) but is discontinued, so only consider it used; the KEF Q3 Meta is still sold new at $899.99.
The Revel Concerta2 M16 is the better-sounding option. An affordable bookshelf speaker with essentially flat mids, a pleasing in-room balance with extra bass, and low distortion. The tradeoff: Harmonic distortion shows a notable peak around 80Hz and a sharp spike around 350Hz, plus the woofer appears to get a bit unhappy right before handing off to the tweeter.
The KEF Q3 Meta is the deeper-bass choice. Coaxial bookshelf speakers with very wide dispersion, punchy kick drums and bass tuning that works close to a wall. Its bass reaches about 52Hz before falling 3dB, against 60.1Hz for the Revel Concerta2 M16. The catch: Not well suited to high-output use: compression and strain in the 1-2kHz region emerge above about 90dB at 10 feet, so a high-output home theater setup isn’t the best application.
Buy the KEF Q3 Meta new; the Revel Concerta2 M16 is no longer sold new, so it only makes sense as a used find.
